11478984 ÷ 243 
Let's see how many times 243 fits into 11478984.

On to step 1:
When dividing 1 by 243, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 243

Going ahead to step 2:
243 can be fit into 11 0 times, resulting in a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 243

Moving on to step 3:
If we divide 114 by 243, we get 0 and a remainder of 114.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 114, we end up with 114.
Include the next digit (7) from the dividend after 114, then repeat: 1147 / 243

Step 4:
243 can be fit into 1147 4 times, resulting in a remainder of 175.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 972 away from 1147, we end up with 175.
Grab the next digit (8) from the dividend, add it to 175, then carry on: 1758 / 243

Let's proceed to step 5:
When dividing 1758 by 243, we get 7 with a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 47.0
Subtracting 1701 from 1758 leaves us with 57.
Append the next digit (9) from the dividend to 57 and continue with: 579 / 243

Advancing to step 6:
243 can be fit into 579 2 times, resulting in a remainder of 93.
Put 2 as the next digit of the answer. 
Result so far: 472.0
Subtracting 486 from 579 leaves us with 93.
Include the next digit (8) from the dividend after 93, then repeat: 938 / 243

On to step 7:
The number 243 fits into 938 3 times, leaving a remainder of 209.
The number 3 becomes the next digit in our result. 
Result so far: 4723.0
If we subtract 729 from 938, we get 209.
Include the next digit (4) from the dividend after 209, then repeat: 2094 / 243

On to step 8:
2094 divided by 243 is 8 with a remainder of 150.
The number 8 becomes the next digit in our result. 
Result so far: 47238.0
If we take 1944 away from 2094, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 9:
243 goes into 1500 6 times with a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 47238.6
If we take 1458 away from 1500, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 10:
If we divide 420 by 243, we get 1 and a remainder of 177.
Write down 1 as next digit of the result. 
Result so far: 47238.61
Subtracting 243 from 420 leaves us with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Let's proceed to step 11:
When dividing 1770 by 243, we get 7 with a remainder of 69.
Put 7 as the next digit of the answer. 
Result so far: 47238.617
Subtract 1701 from 1770 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 12:
When dividing 690 by 243, we get 2 with a remainder of 204.
Use 2 as the next digit of our solution. 
Result so far: 47238.6172
Subtracting 486 from 690 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 13:
When dividing 2040 by 243, we get 8 with a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 47238.61728
If we subtract 1944 from 2040, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 14:
960 divided by 243 is 3 with a remainder of 231.
Record the quotient 3 as the next digit in the result. 
Result so far: 47238.617283
If we subtract 729 from 960, we get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Going ahead to step 15:
If we divide 2310 by 243, we get 9 and a remainder of 123.
Put 9 as the next digit of the answer. 
Result so far: 47238.6172839
If we subtract 2187 from 2310, we get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

On to step 16:
243 goes into 1230 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 47238.61728395
If we subtract 1215 from 1230, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 47238.61728395 with a remaining 1.5e-08.
